1. how many grams of chlorine gas can be produced when 50.0 grams of aluminum chloride decompose 2AICI3 --> 2AI + 3CI2

2. In a laboratory experiment, when 35.0 g mg reacted in excess o2, the percent yield of mgO was 90.0% What was the actual yield of that experiment?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .
